Look more closely, and remember that 8-1 is _not_ the root hub (it is the device plugged into port 1 of the root hub for bus 8): usb8 1d6b:0002 09 2.00 480MBit/s 0mA 1IFs (xhci_hcd 0000:1a:00.0) hub 8-1 2109:3431 09 2.00 480MBit/s 100mA 1IFs () hub usb9 1d6b:0003 09 3.005000MBit/s 0mA 1IFs (xhci_hcd 0000:1a:00.0) hub 9-1 2109:0810 09 3.005000MBit/s 2mA 1IFs (VIA Labs, Inc. 4-Port USB 3.0 Hub) hub 9-1.2 0bc2:50a1 00 3.005000MBit/s 0mA 1IFs (Seagate FA GoFlex Desk NA0JRATK) usb8 is the high-speed part and usb9 is the SuperSpeed part of the XHCI controller. > So either the split roothub code isn't working properly, or > you didn't take the whole patchset.
